I can say one thing for sure, BrlTTY is still running, the process was still
shown in the task manager when Braille froze. Although the process was still
running I don't know whether BrlTTY was still responding.

As I said I am running this on a Windows7 64-bit system and can only test
it
with an ALVA 544T display through USB (the Windows7 system has no serial
port). I have not got any other screen reader or software which will use
the
Braille display installed and also do not have the libusb filter driver
installed (as recommended in the BrlTTY installer). I have the BrlTTY
service installed so that BrlTTY starts when windows starts.
I have taken a NVDA log file of when the freeze of Braille occurs but I am
unable to find anything unusual going on in that. However I am not yet
ruling it out as a NVDA bug. Could anyone give me suggestions on how to
try
and find the source of this bug.
I don't know much about Windows, but is there an equivalent to the Linux
syslog facility that you could check for reports of segmentation faults?
This
will tell you if BRLTTY is crashing for some reason, although one would
expect
your screen reader to complain if it loses its connection to Brlapi.
